I contacted the vendor earlier today before I posted here and did some tests. He made me try it on a windows machine. Which I do have an old laptop running xp. It came up with device has malfunctioned. Device manager showed vendor ID 0000 PCI ID 0000. I suspect this device was DOA. He said he will ask around to see if others have seen this. I'm hoping this is not common for this device. I've had very good luck with Newegg stuff. The price is really nice but this shows reduced from like $30 to $15 so I'm concerned something is up. This is the initial phase of whole house audio so I really can't get people mad at me while development takes place.
